Hi @t-oster,
Can you verify if you have libv4l / libv4lconvert and all its related dependencies installed?
From the error I see in the stack trace, I conclude the problem is caused by missing dependency:
# BridJ: dlopen error when loading /tmp/[directory]/OpenIMAJGrabber.so : /tmp/[directory]/OpenIMAJGrabber.so:
undefined symbol: v4lconvert_enum_frameintervals
The v4lconvert_enum_frameintervals function is part of libv4lconvert, so if it's missing, I guess you have either not installed it yet or installed version is pretty outdated.
I will close this ticket for now, but feel free to reopen it, if dependencies issue is not the root cause of this error.
Cheers!

Hi,
I'm running ArchLinux on the Pi as already said. Libv4l and Libv4l-convert are both present (package v4l-utils provides libv4l=0.8.9). So missing library is not the problem. I can not figure out, why it is not working. I have the same configuration on my Notebook (also ArchLinux) and there it works....

I will provide you small program to be run on your Raspberry Pi so we can diagnose where the problem is located :)

Hi,
I performed a little research and it seams like the *.so object is broken. The previous one was declaring the following:
$ nm -Ca OpenIMAJGrabber.so | grep -i frameintervals
0000ba0c T v4lconvert_enum_frameintervals
And the current one:
$ nm -Ca OpenIMAJGrabber.so | grep -i frameintervals
U v4lconvert_enum_frameintervals
Also the file size is much smaller - 78 kB vs 196 kB.
I will rewert OpenIMAJGrabber.so for ARM 32 to the previous version with hope it will work for you, however you can notice possible side effects in form of the problem described in #9.

Hi,
thanks for the quick repies and the work. I will test it as soon as I have time (probably tomorrow...)..

Fixed in 3474a01
You can use the new version in two ways:
- Download source code and build it locally, or
- Use precompiled JARs located here.
Since this is critical issue for all Raspberry Pi users who are willing to use Webcam Capture (vide @hepin1989), I will upload it to Maven Central ASAP, but first I want to confirm it fix the issue you reported.
If this was the root cause I will also report it in OpenIMAJ project so they will be aware of incorrect *.so in their repo.
Thank you!

I can confirm that it works now on the raspberry pi

Thank you @t-oster !!
Reported in OpenIMAJ as OP-48.
I will release 0.3.8 including commit 3474a01 ASAP, so Raspberry Pi users will not be affected by this bug.
